Step-by-step explanation:

Blank C :

Given total = 68

No. of TV news = 13

Therefore, in Internet it would be = Total - TV news

= 68 - 13 = 55 (ans)

Blank D :

No. of Internet news in 7th grade = 55

No. of Internet news in 8th grade = 64

Hence, total Internet base news = 64 + 55 = 119 (ans)

Blank B :

All total = 138

Internet news total = 119

Hence, TV news total = All total - Internet news

= 138 - 119 = 19 (ans)

Blank A :

No. of TV news in 7th grade = 13

Total news in TV = 19

Therefore, no. of TV news in 8th grade = 19 - 13 = 6(ans)

Blank E :

All total = 138

Total of 7th grade news = 68

Hence, total of 8th grade news = 138 - 68

= 70 (ans)

Question is attached!

Answer:

$3,000 was invested in the account that gained 13%

$17,500 was invested in the account that lost 10%

Step-by-step explanation:

Let the amount in both accounts be x and y

x for the first and y for the second

Adding both is 20,500

x + y = 20,500 •••••(i)

First account earned 13% profit

= 13/100 * x = 0.13x

Second account, a loss of 10%

= -10/100 * y = -0.1y

Total loss of -1,360

This is;

-0.1y + 0.13x = -1,360 •••••••(ii)

From i, x = 20,500-y

Insert this into ii

-0.1y + 0.13(20,500-y) = -1,360

-0.1y + 2665 -0.13y = -1360

-0.23y = -1360-2665

-0.23y = -4025

y = -4025/-0.23

y = 17,500

To get x, we have

x = 20,500 -y

x = 20,500- 17,500

x = 3,000

You invest an initial $2,000 in an account that has an annual interest rate of 6%, compounded daily. How much money will you hav

AleksAgata [21]

The total amount of money earned after 15 years is given by the formula:
A=p(1+r/100)^n
where:
p=principle=$2000
r=rate=6%
n=time=15 years
thus;
A=2000(1+6/100)^15
A=2000(1.06)^15
A=$4,793.12

The local radio station is giving away some tickets to the circus. Adult tickets cost $8 each and children's ticket cost $6 each

X=22
y=3
Pardon if I am wrong, but all you do is divide 172/8 then divide that by 6. Good Luck.

What is the solution to the system of equations below? y = negative one-third x + 9 and y = two-thirds x minus 12 (21, 2) (21, –

lora16 [44]

Answer:

(21, 2 )

Step-by-step explanation:

Given the 2 equations

y = - $\frac{1}{3}$ x + 9 → (1)

y = $\frac{2}{3}$ x - 12 → (2)

Substitute (2) into (1)

$\frac{2}{3}$ x - 12 = - $\frac{1}{3}$ x + 9 ( add $\frac{1}{3}$ x to both sides )

x - 12 = 9 ( add 12 to both sides )

x = 21

Substitute x = 21 into either of the 2 equations and evaluate for y

Substituting into (2)

y = $\frac{2}{3}$ × 21 - 12 = 14 - 12 = 2

Solution is (21, 2 )
